Daron® 5195, a high-performance hybrid system resin, is the Component A in a high-performance hybrid system. This resin system features a unique chemical structure; during curing, the free-radical polymerization of unsaturated resins proceeds concurrently with the chemical polymerization of the polyurethane system, resulting in products with excellent mechanical properties and high-temperature resistance.
Typical Applications
Daron® 5195 resin is suitable for a variety of molding processes, but is particularly well-suited for pultrusion and wet compression molding.
It uses a polyisocyanate resin as the second component.
Characteristic Properties
- Low viscosity eliminates the need for high traction even at high fiber content
- Good wetting and interfacial adhesion ensure excellent mechanical properties
- Excellent high-temperature resistance
- Low volatility and low odor
- Less selective regarding the type of fiber sizing agent
- Excellent adhesion to various fibers, including glass fiber and carbon fiber
Product Description
Daron® 5195 resin has low viscosity and can undergo dual curing at extremely high speeds in thermoforming processes such as pultrusion.
The low viscosity of Daron® 5195 ensures wetting stability at high fiber content, resulting in high-strength products.
Due to its high heat resistance, Daron® 5195 retains a high strength retention rate even at elevated temperatures.
The unique curing process of Daron® 5195 maintains product stability at higher pultrusion speeds, thereby reducing production costs.

Processing Guidelines
- As Component A of a hybrid system, Daron® 5195 should be used in conjunction with a specified type of isocyanate component during the pultrusion process.
- The Daron® 5195 hybrid system resin is better suited for injection pultrusion. When using the conventional dip-pultrusion process, close attention should be paid to changes in resin viscosity and the stable service life of the resin in the feed tank.
- The workshop temperature should be maintained between 18°C and 32°C, and the humidity should be maintained between 40% and 90%. Maintaining stable workshop conditions helps manufacturers produce high-quality products.
